Voltage Sensor Relay

The ICS K Series voltage sensor relay is a sensor that monitors line voltage and provides a relay contact when the line reaches a predetermined level. The pickup voltage setting is adjustable and determines the point of transfer as the input increases. Dropout voltage is fixed as a percentage of the pickup and controls retransfer as the input decreases.

When the pickup level is detected, the sensor energizes the relay coil and the contact transfer is made. When the dropout level is detected, the sensor retransfers the contacts to the de-energized state of the relay. A voltage sensor relay can be used to transfer between preferred and alternate voltage sources. It could also be used as a line monitor that detects a low or high voltage condition of a single phase or three phase source.
